Patent GB-673216-A (GB)
Title: Improvements in or relating to blast guns
Inventor: KEEFER WALTER LYNN
IPC: B24C5/04
Filed: 1950-02-17
Abstract: 673,216. Sand-blast. PANGBORN CORPORATION. Feb. 17, 1950, No. 4102/50. Class 60. A high velocity blast gun has secured on its nozzle in radially spaced relation thereabout a member which extends beyond the end of the nozzle and has a bore gradually tapering away from the nozzle end to a diameter greater than that of the nozzle outlet. A blast gun comprises a jet 26 disposed in a chamber 27 and projecting at high velocity a stream of liquid under pressure, such as water 28, from a pipe 29 into the nozzle 15. An abrasive, such as wet sand 30, is led into the chamber 27 through a pipe 31. The abrasive mixes with the liquid in chamber 27 and is projected through the nozzle 15. An elongated tubular member 11 has a rear end 14 larger than the outlet end of the nozzle 15 of the gun. The inner wall of the rear end 14 is provided with a group of inwardly projecting fins 16, secured to or integral with the rear end 14, and their inner edges 17 fit snugly about the outlet end of the nozzle 15. Shoulders 18 are provided within rear end 14 to engage the nozzle tip 19 when the latter is properly inserted in the rear end 14, thereby making it easy to dispose the member 11 or the nozzle in the proper relative position. The nozzle and member are held together in this relationship by a set screw 20. The spaces between the fins 16 are open to atmosphere through openings 21 and also communicate through openings 23 with the bore 22 of the discharge end 12. The bore 22 has a gradual taper from its rear to its forward tip 24 where the diameter is greater than that of the nozzle outlet 25. In operation, as the stream 13 of mixed liquid and abrasive from the nozzle lo passes through the bore 22, it induces a flow of air from the atmosphere through the channels between the fins 16; the indrawn air passes through the bore 22 and is trapped between its wall and the stream 13 passing therethrough. Since the cross-sectional area of the bore decreases toward its tip but is always greater than the nozzle outlet, the trapped air becomes more and more compressed, and the pressure created by 'the compression tends to maintain the liquid and abrasive stream in a concentrated state.

Abstract: 952,534. Hospital beds; surgical tables. EDWARD DOHERTY & SONS Ltd. Feb. 5, 1963 [Feb. 5, 1962], No. 4359/62. Headings A4H and A4J. [Also in Division F2] A hospital trolley comprises a wheeled chassis frame 1 and a platform 2 pivoted on a transverse axis 3 to the chassis frame at about the middle of its length so that a patient lying on the platform can be tilted through a required angle, means being provided for retaining the platform in a horizontal position or in any one of a number of tilted positions, a double acting spring counterpoise or damper 5 being provided to yieldingly resist tilting of the platform in either direction from the horizontal and to assist restoration of the platform to the horizontal. As shown in Fig. 2 the damper comprises a telescopic device consisting of tubes 7, 8 containing a spring 15 which resists extension of the device and a spring 14 which resists contraction of the device. The tube 7 is pivotally connected to the platform 2 and the tube 8 is pivotally connected at 11 to the chassis frame of the trolley. The springs 14, 15 are unstressed when the platform is horizontal. The platform may be prevented from pivoting about the axis 3 by making the damper 5 rigid. This is effected by means of a bolt 19 which is urged by a spring 20 mounted on the tube 7 into one of a number of holes 18 formed in the tube 8. The bolt 19 may be released from the hole 18 by means of a ramp 22 which is normally held away from the bolt 19 by a spring 29, the ramp being mounted on a rod 23 which may be pulled against the action of the spring 29 by actuating a lever 24.

A metal mounting member, which is secured, without cementing or grouting, to an insulator 8 having at least one annular groove 12, comprises a nut 2 held non-rotatably in an axial recess 11 at one end of the insulator, a bolt 4 which engages the nut and passes freely through an axial hole in a multi-part inner cap 5, and an outer cap 7 which is screwed on to the bolt so as to hold the parts together and to the insulator. The recess 11 may be of polygonal shape, corresponding to nut 2, and the end is widened out into a circular recess 10. A washer 1 is placed beneath nut 2 and an annular washer 3 thereover. The cap 5, which is in two parts, is placed over the end of the insulator, with inwardly-directed rib 18 engaging the annular groove 12. Pins 6 are pushed into holes 13 in the cap and openings in the washer 3. The outer cap 7 is placed over the assembly and the bolt 4 screwed in to butt against the washer 1. A similar member may be applied to the other end of the insulator. The annular groove 12 may take various forms, the rib 18 being shaped accordingly. The bolt 4 may be cut off flush with the outer face of cap 7, which may have threaded holes therein to receive cable supports. Alternatively the bolt may be secured to a supporting bracket or its outer end may terminate in an eyelet, or be shaped to receive the tail end of a similar bolt on another insulator.
